Kinetics of nuclear magnetization in a disordered conductor
Vodop'yanov B. P. , Zhikharev V. A. , Khaliullin G. G.
Large-scale fluctuations in the Korringa relaxation rate in a dirty conductor cause a nonexponential decay of the nuclear magnetization. The spin diffusion of the nuclei, which completely determines the asymptotic behavior after a long time, plays an important role.
